About this tool
Convert any date and time from one timezone to another. This tool uses the Intl API built into your browser, which means it has access to the full IANA timezone database with current DST rules and historical offset changes. You do not need to manually calculate UTC offsets or remember when clocks change.
This is useful when scheduling meetings across time zones, checking what time a live event starts in your local time, or verifying timestamps from logs that use a different timezone. Select your source and target timezones from the dropdown, enter a date and time, and the converted result appears immediately. All computation happens client-side in your browser.
Frequently asked questions
How does the timezone converter handle daylight saving time?
The tool uses the browser's Intl API, which references the IANA timezone database. This database tracks the exact dates and rules for DST transitions in every timezone, so conversions automatically account for whether DST is active on the date you enter.
What timezone names can I use?
The tool uses IANA timezone identifiers like "America/New_York," "Europe/London," and "Asia/Tokyo." These are the same identifiers used in most programming languages and databases. A dropdown lists the most commonly used ones.
Why does the converted time sometimes land on a different date?
Large timezone offsets can push the result into the previous or next calendar day. For example, 11:00 PM in London is already the next morning in Tokyo. This is normal and reflects the actual time difference.
